Album
–
Album, is a collection of audio recordings issued as a single item on CD, record, audio tape, or another medium. Albums of recorded music were developed in the early 20th century, first as books of individual 78rpm records, vinyl LPs are still issued, though in the 21st century album sales have mostly focused on compact disc and MP3 formats. The audio cassette was a format used from the late 1970s through to the 1990s alongside vinyl, an album may be recorded in a recording studio, in a concert venue, at home, in the field, or a mix of places. Recording may take a few hours to years to complete, usually in several takes with different parts recorded separately. Recordings that are done in one take without overdubbing are termed live, the majority of studio recordings contain an abundance of editing, sound effects, voice adjustments, etc. With modern recording technology, musicians can be recorded in separate rooms or at times while listening to the other parts using headphones. Album covers and liner notes are used, and sometimes additional information is provided, such as analysis of the recording, historically, the term album was applied to a collection of various items housed in a book format. In musical usage the word was used for collections of pieces of printed music from the early nineteenth century. Later, collections of related 78rpm records were bundled in book-like albums, the LP record, or 33 1⁄3 rpm microgroove vinyl record, is a gramophone record format introduced by Columbia Records in 1948. It was adopted by the industry as a standard format for the album. Apart from relatively minor refinements and the important later addition of stereophonic sound capability, the term album had been carried forward from the early nineteenth century when it had been used for collections of short pieces of music. Later, collections of related 78rpm records were bundled in book-like albums, as part of a trend of shifting sales in the music industry, some commenters have declared that the early 21st century experienced the death of the album. Sometimes shorter albums are referred to as mini-albums or EPs, Albums such as Tubular Bells, Amarok, Hergest Ridge by Mike Oldfield, and Yess Close to the Edge, include fewer than four tracks. There are no rules against artists such as Pinhead Gunpowder referring to their own releases under thirty minutes as albums. These are known as box sets, material is stored on an album in sections termed tracks, normally 11 or 12 tracks. A music track is a song or instrumental recording. The term is associated with popular music where separate tracks are known as album tracks. When vinyl records were the medium for audio recordings a track could be identified visually from the grooves

Music of Croatia
–
In Croatia both pop and rock are popular, as well as pop music influenced by Dalmatian or Slavonian folk elements. Since the mid-20th century, schlager and chanson-inspired music have formed the backbone of the Croatian popular music, the oldest preserved relics of musical culture in Croatia are sacral in nature and represented by Latin medieval liturgical chant manuscripts. They reveal a wealth of influences and liturgical traditions that converged in this region. Early in the 15th century the ideas of Humanism in Croatia brought about changes to the world of music, interest in music began to spread outside of monastic and church walls with growing influence of new spiritual tendencies from Central European and particularly Italian cities. Humanists and philosophers promulgated new musical theories and aesthetic ideas, Federik Grisogono, Pavao Skalić, julije Skjavetić from Šibenik published his madrigals, while his Motetti a cinque et a sei voci, are characterised by a lavish polyphonic structure under the influence of the Dutch school. Music and dance were a component part of expression, while the function of music. The most prominent Croatian composers of this period include Ivan Lukačić, Vinko Jelić, new tendencies of early Baroque monody soon found their way into the domestic musical tradition, both sacral and secular. The Franciscans and Paulists cultivated sacral chants, mostly monophonic and without organ accompaniment, also, worth mentioning is Ragusino Vincenzo Comnen, the only representative of the music of the Dubrovnik nobility. The tradition of the Baroque was more lasting in church/sacral music, the preservation of music manuscripts and prints became widespread practice in the mid-18th century. They were mostly organists and maestri di cappella, skilful composers who had small vocal and/or instrumental ensembles, in addition, public balls and other events were organised with the participation of local and foreign musicians including the private collection of music materials for playing music at home. Many Italian and domestic musicians worked in Dubrovnik, in the choir and orchestra, in the dukes orchestra, at private. An excellent early example of pre-classical symphony and chamber music was given by Luka Sorkočević, a nobleman educated in Rome, as well as his son Antun, a historian and diplomat. Accordingly, in 1846 Josip Runjanin put to music Antun Mihanovićs 1835 poem Horvatska domovina, in such a setting Vatroslav Lisinski composed the first Croatian national opera Ljubav i zloba, which premièred in Zagreb in 1846. Finally, owing to the founder of Croatian ethno-musicology and musical historiography, Franjo Kuhač and it is a very passionate form of singing, which is one of the reasons it has been limited in popularity to small towns. Even though it is a unique and autochthonous form of singing by Croats, however, several popular Croatian musicians have incorporated some ganga into their work. It can also be heard in music, the American composer Craig Walsh incorporates a ganga-inspired wailing, sighing, pitch-bending. 1, a commissioned for the Sarajevo Chamber Music Festival and the Manhattan String Quartet. Only recently has begun to address political issues, frequently adopting overtly nationalistic overtones

Pop music
–
Pop music is a genre of popular music that originated in its modern form in the United States and United Kingdom during the mid 1950s. The terms popular music and pop music are used interchangeably, although the former describes all music that is popular. Pop and rock were synonymous terms until the late 1960s, when they were used in opposition from each other. Although pop music is seen as just the singles charts, it is not the sum of all chart music. Pop music is eclectic, and often borrows elements from other such as urban, dance, rock, Latin. Identifying factors include generally short to medium-length songs written in a format, as well as the common use of repeated choruses, melodic tunes. David Hatch and Stephen Millward define pop music as a body of music which is distinguishable from popular, jazz, according to Pete Seeger, pop music is professional music which draws upon both folk music and fine arts music. Although pop music is seen as just the singles charts, it is not the sum of all chart music, the music charts contain songs from a variety of sources, including classical, jazz, rock, and novelty songs. Pop music, as a genre, is seen as existing and developing separately, pop music continuously evolves along with the terms definition. The term pop song was first recorded as being used in 1926, Hatch and Millward indicate that many events in the history of recording in the 1920s can be seen as the birth of the modern pop music industry, including in country, blues and hillbilly music. The Oxford Dictionary of Music states that while pops earlier meaning meant concerts appealing to a wide audience. Since the late 1950s, however, pop has had the meaning of non-classical mus, usually in the form of songs, performed by such artists as the Beatles. Grove Music Online also states that, in the early 1960s pop music competed terminologically with beat music, while in the USA its coverage overlapped with that of rock and roll. From about 1967, the term was used in opposition to the term rock music. Whereas rock aspired to authenticity and an expansion of the possibilities of music, pop was more commercial, ephemeral. It is not driven by any significant ambition except profit and commercial reward, and, in musical terms, it is essentially conservative. It is, provided from on high rather than being made from below, pop is not a do-it-yourself music but is professionally produced and packaged. The beat and the melodies tend to be simple, with limited harmonic accompaniment, the lyrics of modern pop songs typically focus on simple themes – often love and romantic relationships – although there are notable exceptions
